The corpus luteum forms and secretes progesterone.

Verified step by step guidance1
Understand the uterine cycle phases: menstrual, proliferative, and secretory. The proliferative phase follows menstruation and precedes ovulation.
Recognize the role of hormones: Estrogen is the key hormone during the proliferative phase, stimulating the thickening of the endometrium.
Identify the physiological changes: During the proliferative phase, the endometrium rebuilds and thickens, preparing for potential implantation of a fertilized egg.
Differentiate from other phases: Unlike the menstrual phase where the endometrium sheds, the proliferative phase involves growth and repair of the endometrial lining.
Connect to the overall cycle: The proliferative phase sets the stage for ovulation, where an egg is released, and the secretory phase, where progesterone further prepares the endometrium for possible pregnancy.
